The TL4242DRJR is an adjustable LED Driver designed to supply high-power LEDs. Protection circuits prevent damage to the device in case of overload, short circuit, reverse polarity and over-temperature. The connected LEDs are protected against reverse polarity as well as excess voltages up to 45V. The integrated PWM input of the TL4242 permits LED brightness regulation by pulse-width modulation (PWM). Due to the high input impedance of the PWM input, the LED driver can be operated as a protected high-side switch.
- PWM brightness regulation
- Low drop voltage
- Open-load detection
- Over-temperature protection
- Short-circuit proof
- Reverse-polarity proof
- Green product and no Sb/Br
Applications
LED Lighting, Industrial, Computers & Computer Peripherals
Warnings This device has limited built-in ESD protection, leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
